[0051] To better understand the technical solution of this application, the following describes the synchronization signal and physical broadcast channel (PBCH) related to this application.

[0052] In order for a terminal (UE) to search for a suitable cell and synchronize with the selected cell, it is usually necessary to broadcast a synchronization signal and provide some main information about the cell.

[0053] The broadcast signal of the 5G NR system is transmitted in the form of SSB, which consists of a synchronization signal (Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS)) and PBCH (PBCH-DMRS, PBCH(data)). The PSS and SSS are used for signal synchronization, while the PBCH is used to transmit system information. The most important system information carried by the PBCH is also called the Master Information Block (MIB).

[0054] In 5G, the structure of SSB is as follows: Figure 2As shown, the SSB consists of 240 consecutive subcarriers (i.e., 20 resource blocks (RBs)) in the frequency domain and four consecutive orthogonal frequency division multiplexing (ORM) blocks in the time domain. The system consists of multiplexing (OFDM) symbols. The PSS (Pressure Sequence of Subcarriers) is a 127-character sequence mapped onto the first OFDM symbol, occupying the middle 127 subcarriers. On either side, 56 subcarriers and 57 subcarriers transmit no signal (i.e., zero). The SSS (Secondary Subcarrier of Subcarriers) is also a 127-character sequence located on the third OFDM symbol of the SSB, occupying the middle 127 subcarriers, with 8 and 9 subcarriers on either side transmitting no signal. The PBCH (Primary Pathway of Subcarriers) is located on the second to fourth OFDM symbols of the SSB. The second and fourth OFDM symbols each have 240 subcarriers, and the third OFDM symbol has 96 subcarriers. Therefore, the PBCH has a total of 576 resource elements (REs). The PBCH demodulation reference signal is... The signal (DMRS) occupies 1 / 4 of the resources, so the number of REs occupied by the PBCH payload is 576*3 / 4=432. Quadrature Phase Shift Keying (QPSK) modulation is used, and the transmission block (TB) size is 864 bits.

[0055] The information carried in the PBCH is mainly the MIB. In 5G NR, the MIB mainly contains the following fields:

[0056] systemFrameNumber: Used to indicate the system frame number;

[0057] subCarrierSpacingCommon: Used to indicate subcarrier spacing;

[0058] ssb-SubcarrierOffset: Used to indicate Kssb;

[0059] dmrs-TypeA-Position: The first DMRS position of PDSCH;

[0060] pdcch-ConfigSIB1: Configuration of Physical Downlink Control Channel (PDCCH) resources related to SIB1;

[0061] cellBarred: Cell Barred flag, used to indicate whether a terminal is allowed to access the cell;

[0062] spare: reserved bits.

[0063] To better understand the technical solution of this application, the narrowband terminal related to this application is described below.

[0064] To support narrowband terminals, the 4G LTE system designed a completely new Narrow Band Internet of Things (NB-IoT) system and a new broadcast signal for it. In subsequent evolutions, the minimum channel bandwidth defined by the NR system is 5MHz. In order to enable narrowband terminals (such as 3MHz terminals) to access the NR system, in the subsequent evolution process, a method of RB-level pruning of PBCH was determined. That is, PBCH encoding is still based on 20 RB resources for encoding and resource mapping, and the SSB structure remains unchanged, but the receiver only receives the PBCH and PSS or SSS within the middle 3MHz (12 RBs).

[0065] To better understand the technical solution of this application, the PBCH DMRS related to this application are explained below.

[0066] The resource mapping method of DMRS in PBCH can be summarized as follows: the resource element (RE) mapping of DMRS is a comb4 structure, that is, the RE interval occupied by two DMRS in the frequency domain is 4 REs. In addition, RE offset can be performed to reduce DMRS interference between neighboring cells.

[0067] Furthermore, the DMRS sequence is a pseudo-random sequence, and its initialization factors include the physical cell identifier (ID), SSB index, half-frame number, etc. When detecting the DMRS, the terminal also infers some or all of the SSB index information.

[0068] To better understand the technical solution of this application, the problems solved by this application are explained below.

[0069] In 6G networks, to support access for narrowband terminals, the SSB received by the narrowband terminal needs to be able to obtain the necessary system messages transmitted within the PBCH, and determine the relevant information indicated by the PBCH DMRS, including the SSB index and timing relationships. Therefore, if the additional PBCH DMRS portion received by the broadband terminal is used to indicate the same information as the narrowband terminal, it will cause information redundancy. In addition, for 6G networks, more scenarios need to be considered, and the amount of information transmitted in the MIB also needs to be reconsidered.

[0070] In this embodiment of the application, by introducing at least two SSB information, SSB information can be flexibly designed for more diverse terminals or broadcast messages, and more broadcast messages can be carried using PBCH DMRS and PBCH load. This allows for more flexible transmission of SSB for more diverse terminals or broadcast messages, and ensures that terminals with different bandwidths can complete the initial access more efficiently.

[0071] The SSB transmission method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0072] Figure 3 This is a schematic flowchart of the SSB transmission method 200 according to an embodiment of this application, such as... Figure 3 As shown, the SSB transmission method 200 may include at least some of the following:

[0073] S210, the first device determines the time-frequency location of at least two SSB information;

[0074] S220, the first device receives at least one of the at least two SSB information based on the time-frequency location of the at least two SSB information;

[0075] Wherein, at least one of the at least two SSB information is part of an SSB.

[0076] It should be understood that Figure 3 The steps or operations of the SSB transmission method 200 are illustrated, but these steps or operations are merely examples, and other operations may be performed in this application. Figure 3 Variations of various operations within it.

[0077] The first device described in the embodiments of this application can be a terminal, or the first device described in the embodiments of this application can be a part of a terminal (such as a sending module, a receiving module, a processing module, etc.), or the first device described in the embodiments of this application can be a component in a terminal, such as a chip.

[0078] In this embodiment, the first device determines the time-frequency positions of at least two SSB information pieces; and the first device receives at least one SSB information piece from the at least two SSB information pieces based on their time-frequency positions; wherein, at least one SSB information piece from the at least two SSB information pieces is part of an SSB. By introducing at least two SSB information pieces, SSB information can be flexibly designed for at least one of the following: more diverse terminals, more granular bandwidth, more layers, and more demanding broadcast messages, thus meeting the SSB requirements of more diverse terminals, more granular bandwidth, more layers, and more demanding broadcast messages. For example, after introducing at least two SSB information pieces, the PBCH DMRS and PBCH load contained in the SSB information can be used to carry more broadcast messages, meeting the SSB requirements of broadcast messages with more layers and more demands. Furthermore, after introducing at least two SSB information pieces, bandwidth can be flexibly designed for different SSB information pieces, meeting the SSB requirements of more granular bandwidth, and ensuring that terminals with different bandwidths can complete initial access more efficiently. For example, by introducing at least two SSB information, parameters related to the SSB information (such as modulation method, coding rate, transmission power, channel or signal multiplexing method, etc.) can be flexibly designed for different terminal types to meet the diverse needs of terminals for SSB.

[0079] In some embodiments, assuming the first device is a narrow-bandwidth terminal, the narrow-bandwidth terminal determines the time-frequency position of the at least two SSB information; and the narrow-bandwidth terminal receives only one of the at least two SSB information based on the time-frequency position of the at least two SSB information, wherein the SSB information received by the narrow-bandwidth terminal can be bandwidth information that satisfies the information received by the narrow-bandwidth terminal, thereby satisfying the narrow-bandwidth terminal's SSB reception requirements.

[0080] The SSB described in this application embodiment can also be called any signal set or signal module that includes at least one of the following: synchronization signal, broadcast signal, PBCH, other system message downlink broadcast channel and its control channel, or control resource set, or control channel search space.

[0081] The at least two SSB information described in the embodiments of this application can be understood as a multi-part SSB; wherein, the at least two SSB information can correspond to one SSB (e.g., corresponding to the same SSB index), and each SSB information can be a part of that SSB; or, a part of the at least two SSB information can correspond to a part of W SSBs (e.g., corresponding to W SSB indices), and another part of the at least two SSB information can correspond to another part of W SSBs (e.g., corresponding to W SSB indices), where W is an integer greater than or equal to 2.

[0082] The at least two SSB information items described in the embodiments of this application may, but not necessarily, have a temporal relationship. For example, the i-th SSB information item and the (i+1)-th SSB information item may indicate two different parts of the resource.

[0083] The embodiments of this application do not limit the bandwidth corresponding to the narrowband terminal. For example, it can be 1.4MHz or 3MHz, or other bandwidths.

[0084] In some embodiments, the at least two SSB information pieces satisfy at least one of the following:

[0085] At least one of the at least two SSB information contains at least one of the channels and signals that is multiplexed with other SSB information.

[0086] The number of channels corresponding to the different SSB information in the at least two SSB information is different;

[0087] The channel resources corresponding to the different SSB information in the at least two SSB information are different;

[0088] The different SSB information in the at least two SSB information correspond to different SSB indices, or the different SSB information in the at least two SSB information correspond to the same SSB index;

[0089] The different SSB information in the at least two SSB information correspond to different beams, or the different SSB information in the at least two SSB information correspond to the same beam;

[0090] The time-frequency resources occupied by the different SSB information in the at least two SSB information are different;

[0091] The modulation schemes corresponding to the different SSB information in the at least two SSB information are different;

[0092] The encoding rates of the different SSB information in the at least two SSB information are different;

[0093] The transmission power corresponding to different SSB information in the at least two SSB information is different;

[0094] The PBCH content contained in the different SSB information in the at least two SSB information is different, or the PBCH content contained in the different SSB information in the at least two SSB information is the same;

[0095] The bandwidths corresponding to the different SSB information in the at least two SSB information are different, or the bandwidths corresponding to the different SSB information in the at least two SSB information are the same;

[0096] The DMRS sequence groups corresponding to the different SSB information in the at least two SSB information are different, or the DMRS sequence groups corresponding to the different SSB information in the at least two SSB information are the same;

[0097] The different SSB information in the at least two SSB information are associated with the same first information, or the different SSB information in the at least two SSB information are associated with different first information;

[0098] The different SSB information in the at least two SSB information are associated with the same first resource, or the different SSB information in the at least two SSB information are associated with different first resources;

[0099] Wherein, the first resource is the resource of the first information;

[0100] The first information includes, but is not limited to, at least one of the following:

[0101] Sounding Reference Signal (SRS);

[0102] Physical Random Access Channel (PRACH);

[0103] Wake-up signal (WUS);

[0104] Physical Uplink Shared Channel (PUSCH);

[0105] Positioning reference signals (PRS);

[0106] Channel State Information Reference Signal (CSI-RS);

[0107] Tracking reference signal (TRS);

[0108] Phase Tracking Reference Signal (PTRS);

[0109] Control Resource Set (CORESET) (such as the CORESET associated with SSB);

[0110] Search space (such as the control channel search space associated with SSB);

[0111] Physical Downlink Shared Channel (PDSCH);

[0112] Uplink control channel;

[0113] Paging Occasion (PO) or Paging Frame (PF);

[0114] System Information (SI) time window or time window used to monitor SI.

[0115] Optionally, the SRS in the first information is used for uplink beam management or positioning.

[0116] Optionally, the PUSCH in the first information can be a Configure Grant Physical Uplink Shared Channel (CG-PUSCH) or a Dynamic Grant Physical Uplink Shared Channel (DG-PUSCH) during a RACH-less handover process; or, the PUSCH in the first information can be a CG-PUSCH or DG-PUSCH during an LTM process; or, the PUSCH in the first information can be a CG-PUSCH or DG-PUSCH during data transmission in an idle or deactivated state; or, the PUSCH in the first information can be a PUSCH for conflict-based access; or, the PUSCH in the first information can be a MsgA PUSCH for two-step random access.

[0117] Optionally, the PRS in the first information is used for positioning.

[0118] Optionally, the CSI-RS in the first information is used for downlink channel measurement or beam management.

[0119] Optionally, the TRS in the first information is used for time and frequency synchronization.

[0120] Optionally, the PTRS in the first information is used for phase estimation.

[0121] Optionally, the PDSCH in the first information can be the PDSCH of System Information Block 1 (SIB1) associated with the SSB. For example, when multiple SSB parts are associated with different SIB1s, the terminal needs to select the corresponding SIB1 based on the measured SSB signal quality and / or signal strength.

[0122] Optionally, the uplink control channel in the first information may be the Physical Uplink Control Channel (PUCCH) associated with the SSB.

[0123] In some implementations, at least one of the at least two SSB information contains a portion of the channel or a portion of the signal, which is multiplexed with other SSB information. This allows for full utilization of each SSB information, optimization of the SSB structure, and saving of resource overhead. It also allows the use of PBCH DMRS and PBCH load to carry more broadcast messages.

[0124] For example, such as Figure 4 As shown, the terminal receives two SSB messages, denoted as SSB message 1 and SSB message 2. SSB message 1 and SSB message 2 multiplex the same PSS and / or SSS. The PBCH content of SSB message 1 and SSB message 2 is segmented and mapped onto two parts of resources that have the same time-domain resources but different frequency-domain resources. Figure 4 In (a) and (b), the PBCH portions of SSB information 1 and SSB information 2 transmit different contents, which, when combined, constitute a complete system message. Figure 4 In (c) of the above, the PBCH portion of SSB information 1 and SSB information 2 transmits the same content. Optionally, in Figure 4In (c), SSB information 2 uses a different modulation scheme and code rate compared to SSB information 1. SSB information 1 corresponds to Quadrature Phase Shift Keying (QPSK) and code rate R, while SSB information 2 corresponds to Binary Phase Shift Keying (BPSK) and code rate 2*R, keeping the transmission block size (TBS) and mapping resources unchanged.

[0125] In some implementations, the number of channels (such as PBCH) corresponding to the different SSB information in the at least two SSB information is different, and the channels corresponding to different SSB information can be flexibly designed based on requirements.

[0126] In some implementations, the channel (e.g., PBCH) resources corresponding to the different SSB information in the at least two SSB information are different, allowing for flexible configuration of the channel resources corresponding to different SSB information. Optionally, the different SSB information in the at least two SSB information corresponds to the same time-domain resources and different frequency-domain resources; or, the different SSB information in the at least two SSB information corresponds to different time-domain resources and the same frequency-domain resources; or, the different SSB information in the at least two SSB information corresponds to different time-domain resources and different frequency-domain resources.

[0127] In some implementations, different SSB information among the at least two SSB information corresponds to different SSB indices, or different SSB information among the at least two SSB information corresponds to the same SSB index. The SSB index corresponding to different SSB information can be flexibly designed based on requirements.

[0128] For example, such as Figure 5 As shown, the terminal receives two SSB messages, denoted as SSB message 1 and SSB message 2 respectively. SSB message 1 and SSB message 2 reuse the same PSS. Figure 5 In (a), the SSS beams of SSB information 1 and SSB information 2 point to different directions, indicating different SSB beams. The PBCH on both sides carries the information of their respective SSB beams. SSB information 1 and SSB information 2 respectively determine an SSB beam or SSB index (as shown in SSB index 0 and SSB index 1 in the figure). Figure 5In (b) of the figure, the SSS beam pointing of SSB information 1 and SSB information 2 are different, but the SSS and PBCH beams of SSB information 1 may be wide beams, while the SSS and PBCH beams of SSB information 2 may be narrow beams. SSB information 1 and SSB information 2 together determine an SSB beam or SSB index (as shown by SSB index 0 in the figure).

[0129] In some implementations, different SSB information in the at least two SSB information correspond to different beams, or different SSB information in the at least two SSB information correspond to the same beam. The beams corresponding to different SSB information can be flexibly designed based on requirements, which can be applied to beam training scenarios as well as beam prediction scenarios.

[0130] In some implementations, the different SSB information among the at least two SSB information occupies different time-frequency resources, thereby allowing the different SSB information to be distinguished based on time-frequency resources.

[0131] In some implementations, the modulation schemes corresponding to different SSB information in the at least two SSB information are different, and the modulation schemes corresponding to different SSB information can be flexibly designed based on requirements.

[0134] In some implementations, the bandwidths corresponding to the different SSB information among the at least two SSB information are different, or the bandwidths corresponding to the different SSB information among the at least two SSB information are the same. The bandwidths corresponding to different SSB information can be flexibly designed based on requirements. For example, some of the SSB information among the at least two SSB information corresponds to narrow bandwidth, and some of the SSB information among the at least two SSB information corresponds to wide bandwidth. Another example is that both of the at least two SSB information correspond to narrow bandwidth, or both of the at least two SSB information correspond to wide bandwidth.

[0135] In some implementations, the DMRS sequence groups corresponding to the different SSB information in the at least two SSB information are different, or the DMRS sequence groups corresponding to the different SSB information in the at least two SSB information are the same. Different DMRS sequence groups corresponding to different SSB information can be flexibly designed based on requirements.

[0136] In some implementations, different SSB information in the at least two SSB information are associated with the same first information, or different SSB information in the at least two SSB information are associated with different first information. The first information associated with different SSB information can be flexibly designed based on requirements to meet the transmission requirements of different services, different terminal capabilities, different system messages, etc.

[0137] In some implementations, different SSB information in the at least two SSB information are associated with the same resources of the first information, or different SSB information in the at least two SSB information are associated with different resources of the first information. The resources of the first information associated with different SSB information can be flexibly designed based on requirements to meet the transmission requirements of different services, different terminal capabilities, different system messages, etc.

[0138] In some embodiments, the PBCH contents contained in the different SSB messages among the at least two SSB messages are different, including at least one of the following:

[0139] The PBCH contained in the different SSB information in the at least two SSB information are associated with different terminal types;

[0140] The PBCH contained in the different SSB information in the at least two SSB information are associated with different service types;

[0141] The PBCH contained in the at least two SSB messages are associated with different system messages;

[0142] Each of the at least two SSB messages contains a PBCH-related system message, wherein the complete system message includes at least two of the aforementioned system messages.

[0143] In this embodiment, the PBCH contained in at least two different SSB information are associated with different terminal types, thereby allowing for flexible design of the terminal types associated with the PBCH contained in different SSB information based on requirements.

[0144] In this embodiment, the PBCHs contained in at least two different SSB information are associated with different service types, thereby allowing for flexible design of the service types associated with the PBCHs contained in different SSB information based on requirements.

[0145] In this embodiment, the PBCHs contained in at least two different SSB messages are associated with different system messages, thereby allowing for flexible design of the system messages associated with the PBCHs contained in different SSB messages based on requirements.

[0146] In this embodiment, each of the at least two SSB messages contains a PBCH-related system message. The complete system message includes at least two of these partial system messages, thereby allowing for flexible acquisition of the complete system message and balancing the load of each SSB message.

[0147] In some embodiments, the PBCH content contained in the different SSB messages among the at least two SSB messages is the same, including:

[0148] The PBCH content contained in the different SSB information of the at least two SSB information is a repeated transmission of a specific system message.

[0149] In this embodiment, the PBCH content contained in at least two different SSB messages is a repeated transmission of a specific system message, which can flexibly realize the repeated transmission of a specific system message and improve the transmission reliability of the specific system message.

[0150] Optionally, the specific system message includes a PBCH payload or a MIB.

[0151] In some embodiments, the above-described S210 may specifically include:

[0152] The first device determines the time-frequency position of the i-th SSB information among the at least two SSB information based on the second information;

[0153] The second information includes, but is not limited to, at least one of the following:

[0154] Information stipulated in the agreement;

[0155] Resource configuration of at least one SSB;

[0156] The synchronization sequence of the at least one SSB;

[0157] The DMRS information of the at least one SSB, or the DMRS information corresponding to the j-th SSB information among the at least two SSB information;

[0158] The PBCH of the j-th SSB information in the at least two SSB information;

[0159] The time-frequency resource interval between each SSB information in the at least two SSB information;

[0160] The time-frequency resource offset value of the other SSB information in the at least two SSB information relative to the j-th SSB information in the at least two SSB information;

[0161] The structure of the at least two SSB information;

[0162] Downlink WUS;

[0163] The time-frequency position of the uplink WUS, wherein the uplink WUS is used to trigger the on-demand SSB;

[0164] The DMRS information includes at least one of the following: DMRS sequence group, DMRS time-frequency location, DMRS frequency domain density, and DMRS port information;

[0165] Where i is a positive integer, and j is an integer greater than or equal to 1 and less than or equal to i.

[0166] In this embodiment, the first device can determine the time-frequency position of the i-th SSB information among at least two SSB information based on the second information, thereby determining the time-frequency position of at least two SSB information.

[0167] Optionally, the j-th SSB information can be the first SSB information among the at least two SSB information, or the j-th SSB information can be the (i-1)-th SSB information among the at least two SSB information. Of course, the j-th SSB information can also be other SSB information, and this application is not limited in this regard.

[0168] In some embodiments, the agreed-upon information includes, but is not limited to, at least one of the following:

[0169] The offset value between the time-frequency position of the i-th SSB information and the time-frequency position of the j-th SSB information;

[0170] The first indication information is used to indicate that the time-frequency position of the i-th SSB information is determined by the PBCH of the j-th SSB information.

[0171] In this embodiment, the time-frequency position of the i-th SSB information among at least two SSB information can be determined based on the offset between the time-frequency position of the i-th SSB information and the time-frequency position of the j-th SSB information, as well as the time-frequency position of the j-th SSB information. Optionally, the time-frequency position of the j-th SSB information can be agreed upon by a protocol, or the time-frequency position of the j-th SSB information can be implicitly or explicitly indicated by the network side.

[0172] For example, in a scenario where the resources of at least two SSB information are contiguous (e.g., the offset is 0), the first device can determine the time-frequency position of at least two SSB information based on the positional relationship of PSS and / or SSS and the resource configuration of at least one SSB (e.g., the time-frequency position of each SSB information can be obtained by dividing the total resources of the SSB by the number of SSB information); or, in a scenario where the resources of at least two SSB information are not contiguous (e.g., there is an offset between SSB information, and the offsets between different SSB information can be the same or different), in this case, the initial search frequency point of the first SSB information among the at least two SSB information can be agreed upon, and then the frequency domain position of each SSB information can be determined based on the offset between the frequency domain positions of each SSB information.

[0173] In this embodiment, the terminal can learn from the first indication information that the time-frequency position of the i-th SSB information can be determined by the PBCH of the j-th SSB information, and thus can determine the time-frequency position of the i-th SSB information after receiving the j-th SSB information.

[0174] In some implementations, the first device can determine the time-frequency position of the i-th SSB information among at least two SSB information based on the resource configuration of at least one SSB. For example, assuming that the synchronization sequences of at least two SSB information are the same, it can be known that the time-frequency resource size of each SSB information is consistent, and the time-frequency position of each SSB information can be determined based on the resource configuration of at least one SSB and the offset between the time-frequency positions of each SSB information or the time-frequency resource interval between each SSB information.

[0175] In some implementations, the first device can determine the time-frequency position of the i-th SSB information among at least two SSB information based on the resource configuration of at least one SSB. For example, assuming that the structures of at least two SSB information are the same, it can be known that the time-frequency resource size of each SSB information is consistent. The time-frequency position of each SSB information can be determined based on the resource configuration of at least one SSB and the offset between the time-frequency positions of each SSB information or the time-frequency resource interval between each SSB information.

[0176] In some implementations, the first device can determine the time-frequency position of the i-th SSB information among at least two SSB information based on the synchronization sequence of at least one SSB. For example, if the synchronization sequences of at least two SSB information are determined to be the same based on the synchronization sequences of at least one SSB, it can be known that the time-frequency resource size of each SSB information is consistent, and the time-frequency position of each SSB information can be determined based on the resource configuration of at least one SSB and the offset between the time-frequency positions of each SSB information or the time-frequency resource interval between each SSB information. As another example, if the synchronization sequences of at least two SSB information are determined to be different based on the synchronization sequences of at least one SSB, and different synchronization sequences correspond to different time-frequency resource configurations, the time-frequency position of each SSB information can be determined based on the synchronization sequences of at least two SSB information. Yet another example, if the synchronization sequences of at least two SSB information are determined to be different based on the synchronization sequences of at least one SSB, and different synchronization sequences correspond to different time-frequency resource position offsets, the time-frequency position of each SSB information can be determined based on the synchronization sequences of at least two SSB information and the time-frequency position of the j-th SSB information.

[0177] In some implementations, the first device can determine the time-frequency position of the i-th SSB among at least two SSBs based on the DMRS information of at least one SSB. For example, if the DMRS information of at least two SSBs is determined to be the same based on the DMRS information of at least one SSB, it can be known that the time-frequency resource size of each SSB is consistent, and the time-frequency position of each SSB can be determined based on the resource configuration of at least one SSB and the offset between the time-frequency positions of each SSB or the time-frequency resource interval between each SSB. As another example, if the DMRS information of at least two SSBs is determined to be different based on the DMRS information of at least one SSB, and the different DMRS information corresponds to different time-frequency resource configurations, the time-frequency position of each SSB can be determined based on the DMRS information of at least two SSBs. Yet another example, if the DMRS information of at least two SSBs is determined to be different based on the DMRS information of at least one SSB, and the different DMRS information corresponds to different time-frequency resource position offsets, the time-frequency position of each SSB can be determined based on the DMRS information of at least two SSBs and the time-frequency position of the j-th SSB.

[0178] In some implementations, the first device can determine the time-frequency position of the i-th SSB information among at least two SSB information based on the downlink WUS. For example, the downlink WUS implicitly or explicitly indicates the time-frequency position of the i-th SSB information among at least two SSB information, or the downlink WUS implicitly or explicitly indicates the time-frequency position of at least two SSB information.

[0179] In some implementations, the first device can determine the time-frequency position of the i-th SSB information among at least two SSB information based on the time-frequency position of the uplink WUS and the offset between the time-frequency position of the uplink WUS and the time-frequency position of the i-th SSB information.

[0180] In some embodiments, the DMRS sequence group corresponding to a portion of the at least two SSB information is used to determine part or all of the content in the SSB index. For example, the DMRS sequence group corresponding to any one of the partial SSB information in the at least two SSB information can be used independently to determine part or all of the content in the SSB index.

[0181] Optionally, the number of bits in the partial SSB information is related to the number of DMRS sequences in the DMRS sequence group. For example, according to the design in 5G NR, each PBCH-associated DMRS sequence group contains 8 DMRS sequences, and 3 bits can be used to determine part or all of the content in the SSB index.

[0182] In this embodiment, the DMRS sequence group corresponding to any one of the partial SSB information in at least two SSB information can be used independently to determine part or all of the content in the SSB index, thereby allowing for flexible design of the DMRS sequence group corresponding to the partial SSB information used to determine part or all of the content in the SSB index.

[0183] Optionally, the DMRS sequence group corresponding to a portion of the at least two SSB information is used to determine other information besides the SSB index (such as cell prohibition flag, system frame number, etc.).

[0184] Optionally, if the DMRS sequence group corresponding to a portion of the at least two SSB information is used to determine a portion of the content in the SSB index, the other content in the SSB index can be determined by other information besides the SSB information.

[0185] In some embodiments, the groups of all DMRS sequences corresponding to the at least two SSB information are used to determine part or all of the content in the SSB index.

[0186] In this embodiment, all DMRS sequence groups corresponding to at least two SSB information can jointly determine part or all of the content in the SSB index.

[0187] Optionally, if all DMRS sequence groups corresponding to the at least two SSB information are used to determine part of the content in the SSB index, the other content in the SSB index can be determined by other information besides the SSB information.

[0188] For example, suppose the first device receives two SSB messages, denoted as SSB message 1 and SSB message 2. The DMRS sequence group corresponding to SSB message 1 is used to determine the high-order bits of the SSB index, and the DMRS sequence group corresponding to SSB message 2 is used to determine the low-order bits of the SSB index. That is, the DMRS sequence groups corresponding to SSB message 1 and SSB message 2 can jointly determine the entire content of the SSB index. Assuming the SSB index is 6 bits long, the DMRS sequence group corresponding to SSB message 1 determines the high-order 3 bits, and the DMRS sequence group corresponding to SSB message 2 determines the low-order 3 bits; together, they determine the entire content of the SSB index.

[0189] In some embodiments, the DMRS sequence group corresponding to the i-th SSB information in the at least two SSB information is used to indicate at least one of the following:

[0190] System frame number;

[0203] Whether the at least two SSB information correspond to wide and narrow beam joint scanning;

[0205] Optionally, the downlink data can be idle or deactivated downlink data, also known as downlink small data transmission. Of course, the downlink data can be other types of downlink data, and this application is not limited to this.

[0206] Optionally, the uplink data can be idle or deactivated uplink data, also known as uplink small data transmission. Of course, the uplink data can be other types of uplink data, and this application is not limited to this.

[0207] In this embodiment, after the first device obtains the cell barred flag, it does not need to decode the PBCH to know in advance whether it can camp on the cell, thus saving the power consumption of the first device.

[0208] Optionally, the configuration information of the uplink WUS includes at least one of the following:

[0209] Uplink WUS configuration identifier, used to indicate one of at least two uplink WUS configurations;

By introducing at least two SSB messages, the SSB messages can be flexibly designed for at least one of the following: more diverse terminals, more granular bandwidth, more layers, and more demanding broadcast messages, thus meeting the SSB requirements of more diverse terminals, more granular bandwidth, and more layers, and more demanding broadcast messages. For example, after introducing at least two SSB messages, the PBCH DMRS and PBCH load contained in the SSB messages can be used to carry more broadcast messages, meeting the SSB requirements of more layers, and more demanding broadcast messages. As another example, after introducing at least two SSB messages, bandwidth can be flexibly designed for different SSB messages, meeting the SSB requirements of more granular bandwidth, and ensuring that terminals with different bandwidths can complete initial access more efficiently. Furthermore, after introducing at least two SSB messages, parameters related to the SSB messages (such as modulation scheme, coding rate, transmission power, channel or signal multiplexing method, etc.) can be flexibly designed for different terminal types, meeting the SSB requirements of more diverse terminals.
